• Performing a fuzzy search may retrieve terms with similar spellings: su ((((sach ky) OR (sac ky))) or (sach ty)) sang ma tai. hieu ve cam xuc va dan vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((((sach ky) OR (sac ky))) OR (sach ty)) sang ma tai. hieu ve cam xuc va dan vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((((sach ky) OR (sac ky))) or (sach ty)) sang ma tai. hieu ve cam xuc va dan vi cua te".
• Adding a wildcard symbol may retrieve word variants: su ((((sach ky) OR (sac ky))) or (sach ty)) sang ma tai. hieu ve cam xuc va dan vi cua te*.
